SPECIFICATION forming part of Letters Patent 0. 377,586, dated February '7, 1888.

Application filed June 23, 1887. Serial No. 242,220. (No model.) i

To aZZ whom it may concern.-

Be it known that we, WVILLIAM J. THOMAS and ELI L. THoMAs, citizens of the United States, residing at Malvern, county of Chester, State-of Pennsylvania, have invented a new and useful Improvement in Fluid- Motors, which improvement is fully set forth in the following specification and accompanying drawings.

, Our invention relates to improvements in vibrating or oscillating water-motors; and it consists' in mechanism, substantially as described and claimed herein, for retaining the buckets in position, so as to carry their'entire load until the completion of the stroke.

It further consistsin mechanism, as claimed,

' for releasing said buckets at the completion of inlet-pipe and motor-shaft.

the stroke, so that the same may be emptied of their contents.

It further consists of the combination and arrangement of parts, as hereinafter fully set forth and claimed.

Figure 1 is a side elevation of our improved motor, showing the left-hand bucket in two positions at the end of the stroke. Fig. 2 is a cross-section of one of the fluid-buckets on line :0 m, Fig. 1. Fig. 3 is a detail section of the Fig. 4. isa crosssection in detail of portions of the motor-arms, showing the inlet-Valves' Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A represents a frame, of iron or any desired material, on which is supported the shaft S. p

B B represent the water or motor buckets pivoted to the pipes O G, as at F F, (see Fig. 2,) the exit of the pipes O 0 being so located as to permitthe water to drop into the elevated bucket F.

D represents an arm carrying a weight, W, and having limbs L L, connected with shaft S, and having rods M M, for attachment to a pump or other desired mechanism to be propelled. Y I

E E represent arms pivoted to the frame of the machine at T 'l", and designed to control the buckets, as will be described hereinafter.

G G are bails attached to the buckets, having a top cross-piece,-B?.

H H represent hook-shaped pieces attached to the ends of the arms E, and having camsurfaces 11'.

K represents a valve with ports K K, adapted to admit the water to the buckets alternately. i

N N represent levers pivoted to the frame at Q, and having rollers -O O, which are held against the arms E E by the action of the spring S. v

U are rollers fixed to standards ZZZ-which are adj ustably connected with the pipes G O.

V V are stops and buffers on the frame for limiting the motion of the water, and prevent.

ing shock to the mechanism.

The operation of the motor is as followsr Water is admitted into the valve'K by means of the inlet-pipe P, and, passing through the port K into the pipe 0, as shown in Fig. 4, is directed into the bucket B until sufficient weight is added to overcome the weighted lever D. Under this state of affairs the lever is advanced, and after passing the center of gravityits weight is added to that of the water, and causes the pipe 0 and bucket B to descend much more rapidly, until finally said pipe strikes the motor-stop V. Simultaneously therewith the bucket Bis tilted automatically,

and the water thereby allowed to flow out,

this being accomplished as follows:

It will be noticed that, owing to the center of motion of the pipes O and CT being below the axis .of the arms E E, as the-said arms and pipes are lowered the distance apart of their extremities is increased.

As the hook-shaped piece H of the lever E freely embraces the bail B on the upright G, it will be clear that as thepipe O descends, the arm E,being of shorter radius, tends to turn the bucket in such position as to keep itlevel, and hence preventthe water from being spilled. At the same time the roller U rides on the left hand portion of the cam-surface I until the .pipe 0 is near its lowest position,'when it strikes the right-hand portion of said camsurface and lifts the lever E, thereby releasing the hook from the cross-piece B of the bail and allowing the bucket B to tilt, owing to the greater weight of water in the right-hand end thereof. It then-assumes a position similar to that of bucket B, (seen on the left-hand side of the figure in dotted lines,) and the water is discharged. Meanwhile the left-hand bucket has ascended and the valve changed its position, so that the port K is in communication with the inlet pipe 1? and pipe 0. Water now enters the pipe 0 and proceeds to fill the bucket B. So the action continues, each bucket in turn being filled and emptied, and the full force of the power due to the weight of all the water being utilized until the stroke is completed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. An oscillating motor having a rocking shaft with weigh ted arm attached thereto,and inlet-pipe with a valve communicating with pipes extending outwardly from said shaft, buckets attached to said pipes, and arms pivted above the center of motion of said pipes and provided with fastening devices having hooked ends adapted to engage bails on said buckets, said parts combined substantially as described.

2. The frame A, having a rocking shaft with weighted arm, in combination with the pipes C 0, having an inlet-pipe with valve communicating with either of said pipes O O, buckets pivoted to said pipes and provided with bails B, pivoted arms E E, having hooked ends with cam under faces, whereby said buckets are held in position, and a guiding device, substantially as described, secured to each of said pipes and adapted to be in contact with the cam under face of said hooked ends of arms E E, substantially as and for the purpose set forth.

3. In a device of the character named, the combination of a frame with a rocking shaft having weighted arm, pipes O G, with inletpipe and valve, the arms E E, having hooked ends and cam under faces, the standards Z Z, with rollers U U, respectively, the springpressed arms N N, bearing on said arms E E,

and buckets pivoted to said pipes C G and having bails B substantially as and for the purpose set forth.

4. The frame A, with a rocking shaft having a weighted arm, in combination with the inlet-pipes G C, an inlet-pipe with valve, buckets pivoted to said pipes C O and having the bails B, the pivoted armsE E, having hooked ends with cam under faces, the standards Z Z, with rollers U U, respectively, and the arms N N, having spring pressing said arms on arms E E, substantially as and for the purpose set forth.

5. An oscillating motor consisting of a frame with rocking shaft having weighted arm, the pipes CG, and inlet-pipe with valve, the buck ets pivoted to said pipes G O and having bails B the pivoted arms E E, with hooked end portions having cam under faces, the adjustable standards Z Z, with rollers U U, and the spring-pressed arms N N, bearing on said arms E E, said parts being combined substantially as and for the purpose described.

6. An oscillating motor consisting of two oppositely extending discharge-pipes having an inlet-pipe with a single valve communicating therewith, a rock-shaft with Weighted arm, buckets eccentrically pivoted to said dis charge pipes, spring pressed arms pivoted above said rocking shaft, and provided with means, substantially as described, attached to their outer ends for retaining said buckets in position to hold theliquid from saiddischargepipes when said buckets are raised, the said means being also adapted to be released from said buckets when they are lowered, substantially as and for the purpose described.
